3 is a circular base, preferably connected to a fixed support 2 by screws 32. 5 is a cylindrical section having an, open upper end and a lower end closed by a web having the hollow cylin- The part 5 fits upon and is permanently secured to the base 3, coaxial therewith and covering the heads of the screws 32. l, 4 are lugs integral with the base 3 within the same. There is a bolt passing through an aperture in one of the lugs 4 then through twoapertures in the walls of the projection 6 and then engaging by screw threads in the other of the projections 4. This bolt secures section 5 in position. 4a are conventional pins of a pin-lock securing the bolt 45 in position so that it cannot be rotated about its axis until the proper key is inserted to adjust the pins in the conventional way. 40

8 is a circular plate fitting upon the upper end of the section 5 with its periphery in a groove in the interior wall of said section at its upper edge. 9 is a delivery spout formed integral with the plate 8, and opening from the upper surface of said plate and laterally. The spout 9 forms a projection from the plate 8 which fits into an opening formed through the wall of the section 5 for that purpose so that the projection 9 forms a delivery spout opening to the out- 5 9a is a cover for the described.

I (Figs. 1, 2, 9, and 12) is a second cylindrical section having its upper end about half open and the other half closed by a web as shown distinctly in Figure 12. The section III has a downwardly extending lug Illa of the form shown in the cross sections Figures 1 and 2, so shaped as to form an annular cavity II'Ib to receive the spring 24 hereinafter referred to.

25 (Figs. 1, 2, and 13) is a thin metal plate,

semi-circular in shape and engaging at its center around a portion of the projection Illa. The spring 24 engages at one end with the section III and at the other end with the plate 25 so as to tend to rotate said plate in the opposite direc-.

tion to the hands of a watch. The plate 25 is provided with a concentric slot 25a through which a screw passes and engages the web of the section I I! as shown in Figure 1, thus serving to limit the motion of the plate 25 about the projection I00.

II is a third section that rests with its lower edge in a groove around the periphery of the section I 0 and concentric therewith. I2 is a glass receptacle for merchandise. This is closed at its upper end and at its lower end is fixed in the section II with its lower edge resting upon an interior circular ledge IIa extending from the inner wall of the section II near its lower end, the ledge Ila is extended for a distance something less than its semi-circumference to form an engaging flange IIab (Figs. 3 and 1).

I8 (Figs. 1, 2, 9, and 11) is a semicircular plate provided with a hub at its center coaxial with the section I6 and provided with a radially extending ridge or shoulder I8b (Figs. 11 and 11b). The two radial edges of the plate I8 extend downward to form lugs I8a (Figs. 11, 11a, and 11b). 23 is a thin arcuate plate secured at a radial edge to the surface of the plate I8 so as to extend beyond the ledge I8b concentric with the plate I8, and forming an opening between said plates beyond said ledge.

I9 is an arcuate plate having the downwardly extending wing I9a at one of its radial edges and having a hub coaxial with the section I0 and plate I8. The plate I9 fits within the space between the plates 23 and I8 with its wing I9a extending downward beyond the edges of said plates.

21 is a cylindrical part having its lower end open and its upper end closed except for an aperture 21a through which the merchandise passes into a receptacle formed within said part by the arcuate plates 21b, which form a receptacle constituting an extension of the aperture 21a. The part 21 has a hub at its center concentric therewith and is located within and coaxial with the section I 8, its lower edge resting in a circular groove near the periphery of the plate 8. 26 is an arcuate plate closing the lower end of the receptacle formed by the parts 21b and forming a surface upon which the lower edges of said parts travel. 210 is a, thumb piece by which the part 21 may be rotated. I6 is a helical spring one end engaging the plate 8 and the other end the part 21, so as to tend to rotate said part in the opposite direction to the hands of a watch.

I is a bolt, screw threaded at its ends and passing through an aperture at the center of the closed lower end of the section and secured therein by a nut I5. The bolt 1 also extends concentrically through openings in the plate 8, the part 21, the section II] and the hubs of the plates I8 and I9. 20 is a washer at the upper end of the bolt I and 2| is a securing nut on the upper end of said bolt. I5 is a wing nut upon the bolt I below the plate 8, its upper end engaging against said plate and I3 is a jam-nut.

The various sections, and the part 21 constituting the delivery part, are bound and secured together by the bolt I and the nuts thereon. The 5 bolt 45 prevents access to the nut I5 to remove the same.

The section III is provided with a cut away portion IIId (Figs. 9 and. 12) in which the thumb piece 210 oscillates in the motion of the delivery 10 part 21. 21) is a pin extending upwards from the part 21 and engaging in an aperture in the wing I9a of the plate I9 so that said plate is carried with the delivery part in its motion.

IIle (Fig. 12) is a slot in the Wall of the sec- 15 tion III in position to permit the passage of the lug or flange 9ab (Figs. 2 and 9). IOf is a second slot in the wall of said section to permit the passage of'the coin. Iflc is a cylindrical lug extending upward from the web of the part III adapted to engage in a corresponding aperture in the plate I8 to fix said plate in position. 2713c (Fig. 14) is a slot extending upward from the lower edge of the wall of the part 21 and 2Ie is a second slot in said wall, these slots register- 25 ing respectively with the slots Ille and Inf in the section III when the delivery part 21 is at the beginning of its stroke. The depression 21d in the web of the part 21 affords space for the movement of the head of the screw passing through the slot 25a in the plate 25 and limiting the movement of said plate.

The nut I5 at the lower end of the bolt I is provided at its lower end with a slot to receive the edge of a screwdriver to adjust said nut in position, to remove, or to tighten the same.

The parts 211) are provided with flanges at their upper ends by which they are secured to the lower surface of the web of the part 2! by screws such as 210 and they may be adjusted toward or from each other to form a smaller or larger receptacle (Figs. 15 and 16) or the plate 26 may be removed and the walls 211) extended clear to the surface of the plate 8 as indicated in broken lines in Figure 15, thus forming a deeper receptacle.

The method of using the above described apparatus is as follows:

The receptacle I2 being filled with the goods, such as nuts or small pieces of confectionery to be delivered, said receptacle is adjusted for placing upon the upper edge of the part III and concentric therewith, the extension I Iab of the ledge IIa passing under and past a radial edge of the plate I8. The nut I5 being slightly loosened the plate I8 may be raised and the extension Ilab of the ledge II a may pass under said plate, the receptacle I2 and part II being turned about its axis until the ends of the said extension come within the lugs I8a. The nut I5 is then tightened up bringing the plate down to position. The lugs I8a then prevent the turning of the receptacle I I, I2, and the plate I8 prevents its being raised vertically.

The delivery part 21 being in its initial position the small articles in the receptacle I2 may fall through the opening 21m and fill the receptacle formed by the plates 2'"). When the coin has been inserted through the slots Inf and 216 the part 21 is rotated by the thumb piece 210 carrying the receptacle formed by the plates 21b to position over the opening 9b of the delivery spout 9 and the articles contained therein will fall into said spout and be retained therein by the lid 9a.

These articles, however, cannot be removed from the spout until the delivery part 21 has returned to its initial position because the cover 9a cannot be raised, the lug Bab striking against the wall of the part 21. But when said part has returned to its initial position the slot Zlbc comes opposite the slot lflc and the cover 9w may be raised, the lug 9ab passing freely through said slots. But when said cover is raised the lug 9ab engaging in the slot 2112c prevents the actuation of the part 21 until the lid is again closed.

When the part 21 is turned about its center it carries the plate IS with it by means of the engaging pin 21 the wing [9a of the plate l9 acting as a stirrer and preventing the clogging of the articles to be delivered.

Should one of the articles to be delivered extend part way into the receptacle in the part 21 it would be engaged by the edge of the opening 21a and the edge of the plate 25 (see Fig. 4) and said plate would be pushed backwards in the further movement of the part 21 against the action of the spring 24. When the part 21 again returns to its initial position, said engaging edges are separated and the article falls into the delivery receptacle without being injured or without having clogged the operation of the apparatus.
